IMPLEMENT FOR APPLYING AND FASTENING PACKAGE BINDERS.

Application filed December 9 1919. Serial No. 343,555.

To all whom it may concern:

Be it known that I, SPENCER C. CARY, a citizen of the United States, residing at the city of New York, borough of Brooklyn,

6 county of Kings, and State of New York,

have invented a certain new and useful Implement forApplying and Fastening Packoperation to fasten, lock or seal the end portions of the binder, more especially after stretching the same tightly around the package a According to this invention, the implement embodies in one 'instrumentality means for placing tension upon the binder, and

means, for fastening the end portions of said the operation of stretching the latter.

The binder-stretching means includes a plurality of movable heads retained in oper ative relation by a guide rod and, each head being provided witha binder-gripping device. In a preferred form, the implement as an entirety is mounted for service over a suitable bench or table by attaching the before mentioned guide rod to a carrying 40 member in the form of a crosshead, the latter being mounted upon a post attached for vertical adjustment in a suitable clamp provided on the bench or table, whereby the entire implement may. be raised or lowered as required to adapt it for use in connectio with boxes etc. of different sizes.

The binder-fastening means is mounted in an operative position with respect to said heads ofthe binder-stretching means, whereby said binder-fastening means is adapted for operation upon theslack or free end portions of a binder the major portion of which is under tension by the action of said binder stretching means. i

The binder fastening means is thus directly associated with or related to the.

stretching means for the performance of its function of looking or sealing the binder prior to releasing said binder from the action of said stretching means. In the several operations, it is desirable that the binder-fastening means he so positioned that in the work of placing tension upon the 'binder said fastening means shall be out of the way of the operator, and to these ends it is preferred to support or mount said binder-fastening means by devices which enable the latter to be shifted at will into an out-of-service relation to the binder-stretching means.

The binder fastening means are embodied in different constructional forms, the form being dependent upon the character of the binder used in connection with the package. In the case of a wire binder, the fastening means embodies a seal retaining member and a plurality of other members mounted for rotative movement with respect to said retaining member and operable at will for bending or twisting the slack or free end portions of said wire binder into looking or interlocking relation to a seal member under the restraint of the first named or retaining member.

For fastening and sealing the end portions of a flat metal band, commonly known as box strapping, the fastening mechanism embodies a plurality of cooperating members and means such as a cam lever or a screw for applying pressure thereto so as to upset the metal of said band end portions and interlock the same with a seal member.

In either form of saidbi-nder lockingmeans the operative parts or elements thereof are supported by suitable means, such as a swinging arm, connected loosely to the guide rodin such manner that said binder locking means may be moved into operative position and then operated to perform the function of fastening or looking the slack end portions of'the binder while the remainder of said binder is under tension.

Furthermore, in either of the preferred forms of the binder fastening means the parts thereof are adapted for use in conj uncrelativelyto'the end portions of a binder,

tion with the binder and with a seal member, the latter being readily positioned in invention will be set forth in the following description taken in connection with the annexed drawings, wherein Fig. 1 is a side elevation of an implement for stretching a binder around a packing case, and for sealing the end portions of said binder in accordance with this invention, said implement being shown in an op erative position with respect to the shipping package resting upon a bench or table.

Fig. 16 is a detail plan view of the flat metal strap and the seal therefor.

The implement is supported in an operative position by a supporting member A shown in Figs. 1, 2 and Gas a horizontal crosshead. Said crosshead is supported by suitable means on a work bench or table indicated at B in Figs. 1 and 2, said supporting means being shown as a post or attached rigidly to the crosshead and fitting in a sleeve Z) secured in a desirable way to one sideof the bench or table. The post a passes loosely through sleeve 6 so that it may be 4 raised or lowered as desired, and the post is held fixedly in position by binding screw 6 supported in sleeve 6 and adapted for frictional contact with the post whereby provision is made for raising and lowering the supporting head A in order that the binder stretching means and the binder locking ,means may be used in connection with packing cases or other shipping packages of different sizes. One of said packing cases is indicated at X in Fig. 1, and it is adapted to receive a binder m which is stretched around the packing case so that the end por tions of the binder may be locked, the binder w of Figs. 1, 2, 3 and 8 being shown as a wire, the ends of which are locked to a seal as, shown in Figs. 1, 3, 8 and 9.

The binder-stretching means illustrated in Figs. 1, 2, 6 and 10 includes a guide rod C, a plurality of gripper heads I), E, and an operating screw F. The guide rod C is rigidly attached to the supporting head A, one end portion of said rod being received in an aperture provided in said head, and the rod being locked in position by a transverse pin a. The gripper heads D, E are fitted loosely on rod C so as to have sliding and rotative movement thereon. Each head D or E is provided intermediate its ends with an opening d which is internally threaded, and at one end said gripper head is provided with a fixed jaw d, see Fig. 6. Said jaw-formed end of the gripper head is provided, also, with a recess 03 and within this recess is positioned a movable jaw d and the head of a cam lever d. The movable jaw (Z is in opposing relation to the fixed jaw (.Z, said aws being relatively positioned to leave an intervening space which opens downwardly, whereby the jaws d d cooperate so as to have engagement with a binder wire a: while the latter is in close relation to or actual contact with the shipping package X, as a result of which the binder can be placed under tension for the major part of its length age. The jaw d is under the action of a Ill?) spring 03, shown in dotted lines in Fig. 6, and with this jaw contacts the cam head d of lever d, said cam head being pivoted to the forked end of thegripper head by atransverse pin 03, see Fig. 6. It will be understood that each head D and E is provided with the fixed jaw and the movable j aw, and, further, that each head is provided with the cam lever d, as clearly shown in Figs. 1, 2 and 10.

The operating screw F is provided with a right-hand thread for a part of its length and with a left-hand thread for another part of its length, said threaded parts of the screw having engagement with the threaded aperture d of heads D, E, respectively, whereby the rotation of the screw imparts relative movement simultaneously to the heads D, E so as to move them toward or from each other, whereby the stretching device is adapted to pull'in two directions upon. the end portions of the binder. The screw is rotated by any preferred means, a crank f being shown. In this invention the binder stretching mechanism is shiftable at will into an out-of-service position with respect to the packing case for the purpose of permitting said packing case to be placed upon table or bench B and the binder a: to. be readily passed around the packing case before bringing the stretcher mechanism into position for service. To this end, the supporting head A is provided with a slot or recess 6, see Fig. 6, the same being of arcuate form andhaving as its axis the centre of the guide rod C. Furthermore, the screw F is provided with a smooth portion f and with a collar f whereby said smooth portion f of the screw is adapted to occupy recess or slot 6 when the binder stretching means is in an operative position. The collar f and an end portion of the crank f engage with the respective sides of the supporting head A when the binder stretcher is in position for service so that the collar and the crank cooperate with the head in precluding endwise movement of the screw in the operationof imparting movement to the heads D E. In order toshift the binder stretching means into the out-of-service position the operator lifts the screw F upwardly and during this lifting movement the gripper heads D E turn freely on the guide red C, the screw F being lifted out of the recess 6 of the supporting head A and the entire device turning on the red C so as to shift the binder-stretching means away from the packing case and thereby expose that part of the packing case around which it is desired to place the binder m preliminarily to the operation of stretching it.

In the construction shown, the operating screw is adapted for supporting a carrying member of the binder-locking or sealing means, and to this end the middle portion of said screw is plain or unthreaded for a part of its length,- as at g, said plain part of the screw being provided with an annular groove, indicated at g in Fig. 3. Onsaid plain part of the screw is loosely fitted a collar g of a carrying member G, shown in Figs. 1, 2, 3 as an arm extending radially from the screw F. This collar of the arm G is free to turn on the plain part of the screw, but said arm is held from sliding movement in a'direction lengthwise of the screw F by a retaining screw y the same being shown in Fig.3 as attached to'the collar 9 and the inner end portion of said screw fitting loosely in the annular groove g,-whereby the arm G is mounted on the screw spindle F in a way to be restrained from sliding along the'plain part 9 of the screw, and at the same time is free to turn upon the screw spindle. The carrying arm G is positioned intermediate the gripper heads D E of the stretching mechanism, and this carrying member supports several parts of the binder locking means so that saidlatter means may in one position operate for thepurpose of bending the free end portions of the binder a, whereas said binder locking means is adapted by theturning movement of-the arm G upon screw spindle F to be shifted into the out-ofservice position when it is desired to stretch the binder around the shipping package.

The carrier arm G'is provided atits free end with a transverse aperture h in which is fitted a stem H held in a fixed pos'tionin the carrier arm by a binding screw it, see F ig. 3. The lower part of this stem is enlarged toiform a'clam'ping member 1, shown more particularly in Figs. 3 and 4, the same being adapted for contactwith a binder seal so as to retain said binder seal in a stationary position during the operation of bending the'end portions of a binder into locking engagement with said seal. The'retain- ,stem is fitted the collar i of a pressure head I, the 'lattenbeingfixedly secured to the stem by ab nding screw i see Fig. 3. The operator applies pressure to the head I, and the stem H, so as to force the retaining member- I into contact with the seal 0:, and while the sealis thus held fixedly in position the pressure of the retaining member thefend'portions of the binder a:

are twisted or bent into locking engagement with the seal w by the action of certain bending membersor .jaws J J which are carried by a-rotatab'le-head J said head,-

and the. two jaws constituting one element shown in detail in Fig. 7. Therotat-able head J is fitted loosely on the lower part of the'stem H so as to occupy the spacebe- &

tween the retaining member I and the free end of the carrying arm G, as shown clearly in Fig. 4, sa d rotatable head J being thus mounted on the stem in a manner for the stem to serve as the axis of rotation of the head. The head J is confined or held against sliding movement by and between the retaining member I and the free end of carrying arm G, but as heretofore mentioned the head is free to turn around the stem H in order that the jaws J J may have rotat-ive movement with respect to retaining member I. The jaws J- J depend from the under face of the rotatable head, and in one position of the head said jaws J J are in alincment with the retaining member I and on opposite sides thereof. see Figs. 4 and 5. The jaws are provided with means for engagement -with the end portions of the binder a, said means be ng preferably in the form of ribs j which depend from the under faces of the jaws. The ribs 7' of the bending jaws are similar to the rib z" of the retaining member, and in the first posi-' for contact with the end portions of the binder. The jaws partake of the rotative movement of the head J in order to tw st or bend the end portions of the binder int-olocking engagement with the seal, as "shown in Fig. 8, said aws being movable in arcuate paths and these paths. are parallel to the plane of the retaining member. Suitable means are provided for imparting rotative movement to the head J 2 and the jaws thereon, and in one embodiment of means shown particularly in Figs. 1, 2, 3, l and 5 said means consists of a lever arm K provided with a hand-grip '70 and attached to a short upstanding post which post is secured to the head J by a transverse pin The lever arm is attached to the rotatable head so as to be entirely out of the way of the gripper heads D E of the binder stretching mechanism, and while the retaining member I is being pressed into contact with the seal this lever arm is operated to turn the head J 2 around stem H, the effect of which is to twist or bend the end portions of the binder :13 around the seal .11 and into locking engagement therewith.

The binder locking or sealing mechanism heretofore described is used in conjunction with a wire binder a! and a seal w, the latter being shown more particularly in Fig. 9. This seal forms the subject matter of a separate application filed on even date herewith, but as herein disclosed the seal is composed of a single piece of metal which is doubled to produce tubular members and an intervening groove 90 see Fig. 9. The operation of the device as thus far described is as follows i The screw spindle F is lifted out of the notch or recess a of the supporting member so that the end portions of the binder overlap. The stretching device is now turned into position for operation, as shown in Figs. 1 and 2, the smooth part f of the screw spindle being received into notch or recess e of head A. The gripper heads D E are positioned into contact substantially with, the top of the case X so that the end portions of the binder x will be received in the spaces between jaws d (Z of the grippers, after which the levers d are turned downwardly so as to move the jaws d toward the jaws d, as a result of which on end portion of the wire is gripped in the head D, whereas the other end portion of the wire is gripped in head E. IVith the seal locking device turned backwardly, the operator fits or adjusts the seal a9 so that the overlapping ends of the bindenwill be loo received in the tubular members of the seal,

the heads D, E toward each other, and thus the binder is stretched in two directions around the packing case, the end portions of the binder sliding through the tubular members of the seal during the stretching operation so as to assume the dotted line position of Fig. 8. The binder locking means is now turned by swinging the arm G around the smooth portion 9 of the screw spindle, the eifect of which is to lower the entire seal locking device into operative position between the gripper heads of the stretching device. The seal-retaining member I engages with the seal so that the rib i of the member I fits in a groove w of the seal, whereas the tubular members of said seal are received in the grooves i in the under face of the retaining member I, the effect of which is to interlock the member I with the seal 00, as shown in Fig. 3. Pressure is now applied by the hand of the operator to the head I in order to forcibly hold the member I in contact with the seal so as to prevent the latter from turning,

v head J 2 around the spindle H, as a result of which the ribs j of the jaws J J will bend the straight end portions of the binder into parallel relation to the tubular members of the seal a2, thereby locking the end portions of the binder to the seal. The arm G is now swung out of position so as to withdraw the bending members and the retaining'member from contact with the seal and the binder, after which the cam levers d of the grippers are operated so as to release the heads D E from the binder, and the entire device including thest-retching means and the bending means are now lifted out of operative position by swinging the screw spindle F upwardly and rearwardly, thus removing th stretching and bending implement from the shipping package and its binder, so that the shipping package can be either removed from the table or reversed in position so that other binders can be applied thereto in the manner described.

In Figs. 10 to 16 there are illustrated,

first, another form of the binder and the seal to be used in connection therewith, and, second, another embodiment of the binder fastening or locking mechanism whereby the seal is compressed and the binder is upset in order to effect the looking or sealing of x the binder, said binder locking mechanism operating in substantially the manner hereinbefore described and being used in con nection .with a stretching mechanism for placing tension upon the binder w. binder shown is a flat metal band Z of a form commonly known as a box strap, the meeting end ortions of said binder being interlocked w1th a seal Z, said seal being shown in Figs. 15 and 16, and the upset portions of the band being shown in-Figs. 11

and 12. The stretching device embodies the I lated thereto, all as hereinbefore described supporting head A guide rod C grippin heads D E, power shrew F and the parts re in connection with the stretching mechanism for placing tension upon theband for the major part of its length by leaving the end portions of said band free or unconfined in order to permit ready application thereto of the seal Z; The binder fastening and sealing means embodies the swinging arm G mounted for 'rotative movement upon the plain and grooved portion g of the screw spindle, but in order to upset the lapping portions of the flat metal band or strap and to interlock the same with the seal I find it desirable to employ the form of binderlocking mechanism illustrated more particularly in Figs. 10, 11, 12, 13 and 14:. Loosely connected with the free end of the carrying member G is a frame member L, the same being provided with an anvil plate M and with an upstanding shank l, to which shank The is pivoted a link N, the latter serving as an operative connection between the frame member and the swinging arm G, whereby same being positioned above the plateM and pivotally connected therewith by a I transverse pin 0, the underface of said anvil 0 being provided with a rib 0 positioned intermediate certain recesses 0 The pivoted anvil O is spaced relative to the anvil'plate M so that the overlapping end portions 2 of the strap Z may be received between the anvil plate M and the anvil O. The frame member L is slotted to receive the head 79 of a cam lever P, the latter being fulcrumed by a pin 7) in the slotted part of the frame member, the head of said cam leve'r being positioned for contact with the pivoted anvil plate 0. A pressure screw may be substituted for cam lever P.

In operation the binder-locking mechanism is swung rearwardly by turning the arm G on the screw'F, and the stretching mecha nism is shifted into an out-of-service position by shifting the screw F out of the notch or recess in the head A.- The box is placed upon the table below the stretching mechanism, and the strap Z is fitted around the box while the stretching mechanism is in said out-of-service position. The stretcher device is swung forwardly and downwardly-in order that the grippers of the heads D E may engage with the band or strap adjacent the overlapping end portions 2 thereof, andthereafter the seal Z is 'toward each other so as to place tension upon the band for the major part of its length, the end portions of said band sliding freely through the seal Z. The stretching operation having been completed so as to place the desired tension upon the band, the binder-locking means are' now swung forwardly so that the anvil plate M passes below the lapping portions of the band, said lapping portions and the sealtbeing re, ceived between the operating faces of the complemental parts M O. The operator now applies power to the lever P, the cam head of which forcibly depresses the anvil 0 upon the seal and the lapping end portions of the binder. anvil plate and the ledge 0" of the anvil act upon the lapped portions of the binder and Cooperating with the anvil plate isa complemental anvil O, the

The ledges m of the upon the seal in a manner to upset the end portions of the binder and to compress the seal, the effect of which is to interlock the two parts of the binder with each other and with the seal, as clearly shown in Figs. 11 and 12. The binder having been stretched, and its ends lockedand sealed, the lever P is operated to release the parts M O, and the binder-locking means are shifted out of the operative position. The cam levers of the gripper heads D E are now released and the stretching mechanism is withdrawn from the binder by lifting screw F out of the notch in the head A, thereby releasing the binder-locking devices and the binderstretching devices and allowing the binder in a locked condition to remain in contact with. the shipping package. Said package may either be removed from the machine or it may be reversed in position below the stretching and locking devices in order that the desired operations may be repeated in connection with another binder.
